ChatGPT Image Generator and Arabic Text: What Works in 2026

01Can the ChatGPT image generator write Arabic text correctly?

It's a question that comes up constantly among designers and store owners in the region: you ask ChatGPT for a poster that says «عرض الصيف» (Summer offer) and the letters come out disconnected, reversed, or with an extra shape that means nothing. Then the next attempt is perfect. What's going on?

The honest answer: modern image models, including the ones inside ChatGPT and Gemini, have become much better at text, and short Arabic headlines often come out right. But it isn't guaranteed every time, and errors grow with longer text, extra lines, and prices or numbers. That isn't a flaw unique to one product; it's the nature of drawing text inside a generated image.

So this article won't tell you one tool always fails and another always works. It explains why Arabic letters break, gives you habits that help everywhere, then compares ChatGPT, Gemini and Vocla using what each company publishes, so you can choose for your own use.

02Why Arabic letters come out broken in AI images

An image model doesn't type text the way a word processor does. It paints a whole picture, and to the model the letters are shapes within that picture. Arabic is harder than English here for concrete reasons:

• Letters change shape: the letter ha looks different at the start, middle and end of a word, and the model has to pick the right form for each position.
• Letters connect: a tiny gap between two letters breaks the word, so a word like «تخفيضات» (sale) looks like scattered pieces.
• Right-to-left direction: if the model mixes up direction, the word comes out mirrored or with letters in reverse order.
• Dots and hamzas: one missing dot turns «خصم» (discount) into a different, meaningless word.
• Numbers and symbols: a price, a percent sign, or Arabic mixed with Western digits all raise the error rate.

That's why one or two words often succeed while a full paragraph on a poster picks up mistakes. The more clearly your prompt pins down the exact text and where it goes, the less the model has to guess.

03Tips for Arabic text in images that work in any tool

Whether you use ChatGPT, Gemini or Vocla, these habits raise your first-try success rate:

1. 1Quote the text: write it «in quotation marks» so the model treats it as literal text to copy, not a description.
2. 2Keep it short: three to six words for a headline. Long details belong in the caption or the message.
3. 3Say where, what colour and how big: «a large white headline at the top» beats «write summer offer».
4. 4One text element per request: a headline, a price, a subtitle and a logo at once multiplies the risk, so start with the headline.
5. 5Write numbers exactly: choose between 30 and ٣٠ and put the exact form inside the quotes.
6. 6Skip full diacritics: lots of vowel marks add small elements that can be drawn wrong.
7. 7Check every letter: zoom in on dots and hamzas before publishing, and retry if needed.

04Gemini images (Nano Banana): what Google says

Google's Gemini app creates and edits images in the chat using models called Nano Banana. According to Google's official pages, free users can create images with Nano Banana 2, and Google lists «better text rendering» with more accurate spelling «for all supported languages» among its features. Those are real strengths: it's free, it sits inside a general assistant, and you edit by chatting.

• Download size: 1K without a plan, 2K with a Google AI plan.
• Daily quota: the help page mentions a daily quota of Nano Banana 2 images and says limits can change.
• Higher models: paid subscribers can redo images with Nano Banana Pro, and Google's overview page says its best model, Nano Banana 2.1, needs a paid plan.
• Watermark: Google says it marks images with an invisible SynthID watermark plus a visible watermark.

05ChatGPT images: what's free and what's paid

ChatGPT's strength is that it's an all-round assistant: write the ad copy, ask for the image in the same thread, then tweak it in plain language. OpenAI's official pricing page sets out how image creation differs by plan:

OpenAI doesn't publish a fixed number of free images on the pricing page; its Free Tier FAQ says image creation has a usage limit separate from text chat. On ownership, OpenAI's Terms of Use assign you its rights in the output, while noting that similar output may be generated for other users.

06ChatGPT, Gemini and Vocla side by side

One point before the table: Vocla doesn't claim a smarter image model than OpenAI or Google. Its Vox Image Pro quality runs on an OpenAI GPT Image model, and Vox Image runs on Google's Nano Banana 2.1. The difference is the workflow built around Arabic:

In short: if you want a quick free image and already live in the assistant, ChatGPT and Gemini are excellent. If you make Arabic designs regularly for a store or business account, a dedicated studio saves steps: the preset sets the size, Arabic text has a clear rule, and background removal, enhancement and turning the image into a video ad in a Gulf or Egyptian voice are in one place, priced in your local currency.

07Which tool to pick for Arabic images

• A quick free test: Gemini or ChatGPT, with the tips above and a short quoted headline.
• Posters with prices and a lot of text: Vox Image Pro in Vocla, the strongest at lettering, and still proofread.
• Editing a product shot while keeping its label: Vox Image in Vocla from Creator, or chat-based editing in the general tools.
• A transparent background for a logo or sticker: Vox Image Pro or Ultra with the transparent option, or Remove background.
• An image that becomes an ad with a Saudi or Egyptian voiceover: Make it a video in Vocla, from Starter.

Still unsure? Run your own test instead of trusting screenshots online: paste the identical prompt, with one short quoted headline, into each tool you're considering, three times each. Zoom in and count how often the headline came out right, dots and hamzas included, and how often it needed a fix. Ten minutes gives you an answer for the designs you actually make, and it's worth repeating every few months because models update.

Whatever the tool, read its commercial-use terms before running a paid ad. In Vocla, commercial rights start at Starter, and images that fail cost nothing.

This comparison is based on the official pages cited, as of October 2026, and doesn't measure output quality in a controlled test. Every tool's results vary by prompt and attempt.
